LTC6078/LTC6079 Micropower Precision, Dual/Quad CMOS Rail-to-Rail Input/Output Amplifi ers
U FEATURES DESCRIPTIO
■
Maximum Offset Voltage of 25µV (25°C)
The LTC®6078/LTC6079 are dual/quad, low offset, low ■
Maximum Offset Drift of 0.7µV/°C
noise operational amplifi ers with low power consumption ■
Maximum Input Bias:
and rail-to-rail input/output swing.
1pA (25°C)
Input offset voltage is trimmed to less than 25µV and the
50pA (≤85°C)
CMOS inputs draw less than 50pA of bias current. The low ■ Micropower: 54µA per Amp offset drift, excellent CMRR, and high voltage gain make ■ 95dB CMRR (Min) it a good choice for precision signal conditioning. ■ 100dB PSRR (Min) ■ Input Noise Voltage Density: 16nV/√Hz Each amplifi er draws only 54µA current on a 3V supply. The ■ Rail-to-Rail Inputs and Outputs micropower, rail-to-rail operation of the LTC6078/LTC6079 ■ 2.7V to 5.5V Operation Voltage is well suited for portable instruments and single supply ■ LTC6078 Available in 8-Lead MSOP and 10-Lead DFN applications. Packages; LTC6079 Available in 16-Lead SSOP and The LTC6078/LTC6079 are specifi ed on power supply DFN Packages voltages of 3V and 5V from –40 to 125°C.
